Specification of Letters Patent. Patented Apr. 27, 1920- Applioati'on filed September 15, 1919. Serial No. 323,779.

ing boxes of the class or type in which the bearing comprises a plurality of adjustable sections, an instance of which is exemplified in Letters Patent 'of the United States No. 1,218,375, granted and issued to me under date of March 6, 1917. The object of my present invention is to provide a driving box of the type referred to, in which the bearings sections shall be mutually adjustable and free to assume their normal positions relatively to the box, and lost motion, resultant upon wear of the box and of the bearings, may, as to both said members, be simultaneously taken up by the ordinary pedestal wedge.

The improvement claimed is hereinafter In the accompanying drawings: Figure 1 is a front View, in elevation, of a locomotive driving box illustrating an embodiment of my invention; Fig. 2, a plan or top view of the same; Fig. 3, a longitudinal central section; Fig. 4, a transverse section, on the line a a of Fig. 3; Fig. 5, a plan view of the left hand section of the driving box; Fig. 6, a front view of the same; Fig. 7, a plan view of the righthand section of the driving box; and, Fig. 8, a front view of the same.

Referring descriptively to the specific embodiment of my invention which is here-V in exemplified, it is, as in Letters Patent No. 1,218,375 aforesaid, illustrated, as applied in a locomotive driving box which is fitted, with the capacity of relative vertical movement, between a shoe, 1, and a wedge, 2, which is operated by a' screw, 2, in a locomotive frame pedestal, the jaws, 3, 3, of which, extend from an upper frame rail, 4, to a lower frame rail, 5. The portion of the weight of the locomotive which ing axle on which the driving box rests, is applied to the top of the driving box through a spring saddle, 7, which fits over the upper frame rail, and supports a drivby the journal, 6, of the -driving spring, which is not shown, in the usual manner.

The driving box proper is made in two independent and relatively movable sections, each of which is of substantially in verted L form, comprisin a top horizontal member, 8, and a vertica side member, 8 integral therewith, and depending, at a right angle, therefrom. As most clearly shown in Fig. 7, the top member, 8, of what may, descriptively, be termed the right hand section of the driving box, is shorter,

in the line of the driving axle, than the top member of the other, or left hand section, and it overlaps, and rests on, the top of the last named member, fitting between end flanges, 8, thereon. A recess, 8 (Fi s. 4. and 6) is formed in the lower face 0 the top member of the left hand section of the box, and stops, 8, are formed on the inner sides of both the sections thereof, at and adjoining their lower ends, the functions of which recess and stops will be presently described.

The journal bearing or brass of the driving box, is formed in three sections, and comprises a top section, 12, which is fitted in the recess, 8 of the top member of the left hand section of thebox, and two side sections, 12, 12 each of which extends both above and below the axial line of the journal, and is fitted between the journal and the vertical side member of one of the sections of the driving box. Undue downward movement of the side sections of'the overlapping sectionsof the driving box, are

relatively adjustable, the journal box sections both horizontally and vertically, and the driving box sections, horizontally.

Proportionately as the top bearing section, 12, wears and becomes thinner, the right and left'hand sections, 8, 8, 8, 8, of the driving box, slide down on the side bearing sections, 12, 12, allowing them to preserve the correct axial relations to the driving axle, and as the side bearing sections wear thinner, the overlapping driving box sections, 8, 8, 8, 8, can be closed in nearer together by adjustment of the pedestal wedge, 2, as stated in thenext succeeding para 'raph.

W en, by'reason of knocking, pounding, or slackness of the bearing on the journal, it becomes necessary or desirable to take up wear or lost motion, the sections of the driving box, and the interposed journal bearing sections, may be manually closed together, by proper adjustment of the pedestal Wedge, 2, by its operating screw, 2. The' same function may, if'preferred, be automatically performed by the application of one of the forms of automatic spring adjusted wedges which are well known and used in railroad practice, for automatically. taking up slack in drivingv boxes of the ordinary construction.

The provision of overlapping top members in the driving box sections, sliding in a horizontal plane immediately above the axis-of the bearing, enables the sections of the driving box to be held together, and at the same time allows adjustment for wear to be taken up by the pedestal wedge, no other adjustment or shimming being necessary, within the capacity of the wedge. Each of the bearing sections is free to move in the driving box, and'its wear will be taken up in relation to the common axial line of the sections. It is well vknown, in practice, that when the ordinary driving box, with semi-circular bearing, becomes hot, it tends to grip the journal, and no meansare available to relieve such gripping. In the operation of m invention,the release of the pedestal we ge simultaneously slacks up the driving box in the pedestal fit and the bearing sections around the journal. The only resistance experienced is that of the sliding of the top sections of the driving box, one on .the other, but when the abutting surfaces are properly lubricated, the co-efficient of the friction will be very low. 1

I claim as my invention and desire to secure Ry Letters Patent:

1. he combination, in a locomotive engine, of a frame pedestal; a driving box located therein, and made in two independent sections, comprising members, one of which overlaps the other and rests thereon, with the capacity of relative horizontal movement; three journal bearing sections,disposed in the top and sides, respectively, of the driving box; means for effecting adj ustment of the bearing sections, relatively to a common axial line; and means for applying weight to the top bearing section.

2. The combination, in a locomotive engine, ofa frame pedestal; a driving box 10- cated therein, and made in two independent sections, comprising members, one of which overlaps the other and rests thereon, with the capacity of relative horizontal movement; three journal bearing sections, disposed in the top and sides, respectively, of the driving box; means for effecting adjustment of the bearing sections, relatively to a common axial line; and a spring saddle, bearing on the top overlapping member of the driving'bo'x.

3. The combination, in a locomotive engine, of a frame pedestal; a driving box located therein, and made in two independent sections, comprising members, one of which overlaps the other and-rests thereon, with the capacity of relative horizontal movement; three journal bearing sections, disposed in the top and sides, respectively, of the driving box, the backs of the side bearing sections being parallel, to afford capacity of vertical adjustment of said sections in the driving box; means for effecting ad justment of the bearing sections, relatively to a common axial line; and means for applying weight to the top bearing section.

5. The combination, in a locomotive engine, of a frame pedestal; a driving box located therein, and made in two independent sections, comprising members, one of which overlaps the other and rests thereon, with the capacity of relative horizontal movement; a wedge interposed between one of the driving box sections and the adjoining j aw of the pedestal; means for;.imparting vertical movement to said wedge, to effect adjustment of the driving box sections, and of the bearing sections, relatively to a common axial line; and means for applying weight to the top bearing section.

6. A locomotive engine driving box, made in two independent and relatively adjustable sections, each of substantially inverted L form, comprising a horizontal top member and-a vertical side member depending therefrom, the top member of one section overlapping and resting on the top member of the other section, and movable in a horizontal plane relatively thereto.
